Abstract
Canon d'arrosage pour tubes à entretien d'image à vision directe, et tubes comportant un tel canon. Une lentille quadrupolaire 5 est incorporée au canon. Le canon permet une commande de la densité d'électrons dans le faisceau d'arrosage dans une plage étendue, par simple action sur le potentiel de la grille de commande 2, sans variation des potentiels d'accélération (électrodes 3 et 4). Application en laboratoire à l'observation de signaux de très courte durée, notamment en électronique rapide.Spray gun for direct vision image maintenance tubes, and tubes incorporating such a gun. A quadrupole lens 5 is incorporated into the barrel. The gun allows control of the electron density in the spray beam in a wide range, by simple action on the potential of the control grid 2, without variation of the acceleration potentials (electrodes 3 and 4). Application in the laboratory to the observation of signals of very short duration, in particular in fast electronics.
